A counterfeiter

A big-city counterfeiter decided the best place to pass off His phony $18 bills would be in some small hick Texas town. So, he got into His new wheels and off he went. He found a tiny town with a single store. He entered the store and handed one of the bogus bills to the man behind the counter. "Can you change this for me, please?" he said. The store clerk looked at the $18 bill a short time, then smiled and told the man, "Ah reckon so, Mister. Ya want 2 nines or 3 sixes?"
